Installation method for inductor of duplexer

Abstract

The invention relates to an installation method for inductor of duplexer, which comprises a cover board of duplexer, two through-hole screws, a block-shaped holding device, a metal wire, a hole filling screw, a spring washer, a metal wire pellet and a pellet fixing screw. The installation method comprises fixing the through hole screws on the cover board of duplexer, locating the block-shaped holding device between the two through hole screws, inserting both ends of the metal wire which has been shaped into two holes at the center of the two through hole screws, arranging the metal wire pellet on the block-shaped holding device, fixing the metal wire on the block-shaped holding device by the metal wire pellet, and jointing the through hole screws and the metal wire by soldering with tin solder. Compared with the prior art, the installation method for inductor of duplexer is characterized by uniform position of welding, which can relieve body harm to people, save inner space, and save tin solder.

Description

technical field [0001] The invention relates to a duplexer inductor, in particular to a method for installing the duplexer inductor. Background technique [0002] The inductance of the duplexer is realized by ordinary screws and welding wires (different shapes and sizes can be made). The currently commonly used duplexer inductor installation has the following defects: [0003] 1. Because both the screw and the metal wire are cylinders, and their contact surface is linear, it will cause difficult operation during welding and cause the welding position of the metal wire to be inconsistent, which will seriously affect the electrical performance index of the product. [0004] 2. Due to the uncontrollability of human factors during the welding process, the metal wire will be skewed, affecting the overall size, and seriously affecting the electrical performance indicators of the product; [0005] 3. Due to the good thermal conductivity of the metal, and the metal wire and the sc...

AI Technical Summary

Problems solved by technology

[0003] 1. Because both the screw and the metal wire are cylinders, and their contact surface is linear, it will cause difficult operation during welding and cause the welding position of the metal wire to be inconsistent, which will seriously affect the electrical performance index of the product

[0004] 2. Due to the uncontrollability of human factors during the welding process, the metal wire will be skewed, affecting the overall size, and seriously affecting the electrical performance indicators of the product;

[0006] 4. When welding, due to the large contact area between the screw and the wire, the area of ​​the welding point is correspondingly large, which will cause shortcomings such as difficult operation of the solder joint, difficulty in cleaning the solder joint, and waste of solder.
